Description

Gaskochmulde Gas cooktop
Die vorliegende Erfindung betrifft eine Gaskochmulde mit einer Muldenplatte, durch die zumindest ein Gasbrenner ragt, welche Muldenplatte von einer hochgezogenen Seitenwand umgeben ist und zumindest eine Luftoffnung aufweistThe present invention relates to a gas hob with a hob plate through which at least one gas burner protrudes, which hob plate is surrounded by a raised side wall and has at least one air opening
Aus der EP 0 554 511 ist ein Gasbrenner bekannt, bei dem ein Brennerstativ eine Gasmulde von unten durchsetzt Den über die Gasmulde hinausragenden Bereich des Brennerstativs umgibt ein Steckaufsatz Im Steckaufsatz können zusätzliche Austπttsoffnungen vorgesehen sein, aus denen Sekundarluft aus dem Muldenraum unterhalb des Brenners zur Flammenkuhlung ansaugbar istA gas burner is known from EP 0 554 511, in which a burner stand passes through a gas trough from below. The area of the burner stand which projects beyond the gas trough is surrounded by a plug-in attachment. Additional outlet openings can be provided in the plug-in attachment, from which secondary air from the trough space below the burner for flame cooling is suckable
Die Aufgabe der vorliegenden Erfindung besteht dann, eine Gaskochmulde bereitzustellen, bei der eine Konvektionsluft von unterhalb der Muldenplatte zur Kühlung von Bauelementen, insbesondere der hochgezogenen Seitenwand in der Gaskochmulde und/oder als Sekundarluft verwendbar istThe object of the present invention is then to provide a gas hob in which a convection air from below the hob plate can be used to cool components, in particular the raised side wall in the gas hob and / or as secondary air
Die erfmdungsgemaße Aufgabe ist durch die Gaskochmulde mit den Merkmalen des Patentanspruches 1 gelost Gemäß dem kennzeichnenden Teil des Patentanspruches 1 weist die Gaskochmulde eine Luftfuhrungsplatte auf, die auf der Muldenplatte angeordnet ist Zwischen der Luftfuhrungsplatte und der Muldenplatte ist ein Zwischenraum ausgebildet, der mit der Luftoffnung in Verbindung steht Der Zwischenraum dient als Luftfuhrungskanal Vorteilhafterweise kann in dem Luftfuhrungskanal Konvektionsluft von unterhalb der Muldenplatte bedarfsweise zu einem Flammenbereich des Gasbrenners, zur hochgezogenen Seitenwand und/oder zu weiteren hitzeempfindlichen Bauelementen der Gaskochmulde gefuhrt werden Der Konvektionsluftstrom ist sowohl durch Zwangskonvektion mittels eines Geblases als auch durch thermische Konvektion erzeugbarThe object according to the invention is achieved by the gas hob with the features of patent claim 1. According to the characterizing part of patent claim 1, the gas hob has an air guide plate which is arranged on the pan plate. An intermediate space is formed between the air guide plate and the pan plate which is in contact with the air opening Connection is established The intermediate space serves as an air duct. Convection air can advantageously be conducted in the air duct from below the trough plate to a flame area of the gas burner, to the raised side wall and / or to other heat-sensitive components of the gas hob. The convection air flow is both by forced convection by means of a blower and by Thermal convection can be generated
Gemäß einer bevorzugten Ausfuhrungsform ist die Stirnseite der Luftfuhrungsplatte über einen Luftspalt von einer Seitenwand der Gaskochmulde beabstandet Dadurch wird ein Teil der Konvektionsluft durch den Luftspalt entlang der Seitenwand nach oben gefuhrt Die Strömung der Konvektionsluft entlang der Seitenwand dient zur Kühlung derselben Dies ist insbesondere von Bedeutung bei einer Gaskochmulde mit tiefgelegt angeordneten Gasbrennern. Hierbei sind die Topfträger nahezu auf einem Höhenniveau mit der daran anschließenden Arbeitsfläche der Arbeitsplatte, während die Seitenwand der Gaskochmulde bis zu einer Oberseite der Arbeitsplatte hochgezogen ist. Bei einer derartigen Anordnung besteht einerseits die Gefahr einer Überhitzung der Seitenwand aufgrund einer verminderten Wärmeabfuhr in die Umgebung außerhalb der Gaskochmulde. Andererseits besteht die Gefahr, dass der Flammenbereich des Gasbrenners nur ungenügend mit Sekundärluft versorgt wird.According to a preferred embodiment, the end face of the air guide plate is spaced apart from a side wall of the gas hob via an air gap. As a result, part of the convection air is directed upward through the air gap along the side wall. The flow of the convection air along the side wall serves to cool the same This is particularly important in the case of a gas hob with gas burners arranged at a low level. Here, the pan supports are almost at a level with the work surface of the worktop adjoining them, while the side wall of the gas hob is pulled up to the top of the worktop. With such an arrangement, on the one hand, there is a risk of the side wall overheating due to reduced heat dissipation into the surroundings outside the gas hob. On the other hand, there is a risk that the flame area of the gas burner is only insufficiently supplied with secondary air.
Zur Verbesserung der Luftkonvektionsströmung zu hitzeempfindlichen Bauteilen, zur Seitenwand und/oder zu dem Flammenbereich des Gasbrenners beträgt in einer bevorzugten Ausführungsform der Abstand zwischen der Luftfuhrungsplatte und der Muldenplatte in etwa 3 bis 10 mm und bevorzugt etwa 5 mm. Der Abstand zwischen der Stirnseite der Luftfuhrungsplatte und der hochgezogenen Seitenwand beträgt zwischen 10 und 30 mm und vorzugsweise etwa 20 mm, damit die Luftkonvektionsströmung entlang der Seitenwand ausreichend ist.In order to improve the air convection flow to heat-sensitive components, to the side wall and / or to the flame area of the gas burner, in a preferred embodiment the distance between the air guide plate and the trough plate is approximately 3 to 10 mm and preferably approximately 5 mm. The distance between the end face of the air guide plate and the raised side wall is between 10 and 30 mm and preferably about 20 mm, so that the air convection flow along the side wall is sufficient.
Die Luftfuhrungsplatte ist vorteilhafterweise durch Segmente gebildet, die zueinander in Anlage sind. Dadurch wird eine leichte Handhabung der Luftfuhrungsplatte bei deren Reinigung gewährleistet.The air guide plate is advantageously formed by segments which are in contact with one another. This ensures easy handling of the air guide plate when cleaning it.
Bevorzugt ist es, wenn unterhalb des Luftspalts zwischen der Stirnseite der Luftfuhrungsplatte und der Seitenwand eine rinnenartige Vertiefung ausgebildet ist. In der Vertiefung sammeln sich die während eines Garbetriebs durch den Luftspalt auf die Muldenplatte tropfenden Verunreinigungen. Dadurch ist verhindert, dass die Verunreinigungen über die Druckausgleichsleitung auf unterhalb der Gaskochmulde angeordnete Küchenmöbel tropfen.It is preferred if a channel-like depression is formed below the air gap between the end face of the air guide plate and the side wall. The impurities dripping through the air gap onto the tray plate collect during cooking. This prevents the contamination from dripping through the pressure compensation line onto kitchen furniture arranged below the gas hob.
Vorteilhaft ist es, wenn die Stirnseite der Luftfuhrungsplatte über einen Luftspalt von einer Seitenwand der Gaskochmulde beabstandet. Ein Teil der Luftkonvektionsströmung kann somit vom Zwischenraum durch den Luftspalt entlang der Seitenwand nach oben strömen. Dadurch wird die Seitenwand in einfacher Weise durch die Luftkonvektionsströmung gekühlt. Dies ist insbesondere von Bedeutung bei einer Gaskochmulde, in der die Gasbrenner tiefgelegt angeordnet sind. Hierbei sind die Topfträger nahezu auf einem Höhenniveau mit der daran anschließenden Arbeitsfläche der Arbeitsplatte, während die Seitenwand der Gaskochmulde bis zu einer Oberseite der Arbeitsplatte hochgezogen ist. Bei einer derartigen Anordnung besteht einerseits die Gefahr einer Überhitzung der Seitenwand aufgrund einer verminderten Wärmeabfuhr in die Umgebung außerhalb der Gaskochmulde. Andererseits besteht die Gefahr, dass nur der Flammenbereich des Gasbrenners nur ungenügend mit Sekundärluft versorgt wird.It is advantageous if the end face of the air guide plate is spaced apart from a side wall of the gas hob via an air gap. Part of the air convection flow can thus flow upwards from the intermediate space through the air gap along the side wall. As a result, the side wall is cooled in a simple manner by the air convection flow. This is particularly important in the case of a gas hob in which the gas burners are arranged low. Here are the The pan support is almost at the same level as the work surface of the worktop, while the side wall of the gas hob is pulled up to the top of the worktop. With such an arrangement, on the one hand, there is a risk of the side wall overheating due to reduced heat dissipation into the surroundings outside the gas hob. On the other hand, there is a risk that only the flame area of the gas burner is insufficiently supplied with secondary air.
Nachfolgend ist ein Ausführungsbeispiel der Erfindung anhand der beigefügten Figuren erläutert. Es zeigen:An exemplary embodiment of the invention is explained below with reference to the attached figures. Show it:

Figur 3 ein vergrößerter Ausschnitt aus der Figur 2.FIG. 3 shows an enlarged detail from FIG. 2.
In der Figur 1 ist eine Gaskochmulde 1 gezeigt, die in eine Arbeitsplatte 3 eingelassen ist und fünf Zweikreis-Gasbrenner 5 bis 13 aufweist. Den Gasbrennern sind in einem oberen Bedienfeld 15 fünf Betätigungsknebel 17 zugeordnet, die der Gasführung und der Zündung der Gasbrenner dienen. Wie aus der Figur 2 hervorgeht, ragen die Gasbrenner durch Montageöffnungen einer wannenförmigen Muldenplatte 19, die aus einem rostfreiem Edelstahlblech gefertigt ist. Die Muldenplatte 19 ist mit hochgezogenen Seitenwänden 21 ausgebildet, deren obere Randleisten 23 auf der Arbeitsplatte 3 liegen. In den oberen Randleisten 23 ist gemäß der Figur 1 das Bedienfeld 15 ausgebildet, in dem die Betätigungsknebel 17 angeordnet sind.1 shows a gas hob 1, which is embedded in a worktop 3 and has five dual-circuit gas burners 5 to 13. In an upper control panel 15, five actuation knobs 17 are assigned to the gas burners, which are used to guide the gas and ignite the gas burners. As can be seen from FIG. 2, the gas burners protrude through assembly openings in a trough-shaped trough plate 19, which is made from a stainless steel sheet. The trough plate 19 is formed with raised side walls 21, the upper edge strips 23 of which lie on the worktop 3. According to FIG. 1, the control panel 15, in which the actuating toggles 17 are arranged, is formed in the upper edge strips 23.
Zum Abstellen von Gargutbehältnissen sind oberhalb der Gasbrenner Topfträger 25 angeordnet, wie sie in der Figur 2 angedeutet sind. Aus optischen Gründen und aus bedientechnischen Gründen ist die Arbeitsfläche der Arbeitsplatte 3 mit den Topfträgern 25 nahezu auf einem Höhenniveau angeordnet. Dies hat zur Folge, dass die Brennerköpfe der Gasbrenner tiefgelegt innerhalb eines Freiraums 27 der wannenförmigen Muldenplatte 19 angeordnet sind, der zwischen der Muldenplatte 19 und den Topftragern 25 angeordnet istTo place food containers, pot supports 25 are arranged above the gas burners, as indicated in FIG. 2. For visual reasons and for technical reasons, the work surface of the worktop 3 with the pot supports 25 is arranged almost at a level. The result of this is that the burner heads of the gas burners are lowered within a free space 27 trough-shaped trough plate 19 are arranged, which is arranged between the trough plate 19 and the pot supports 25
An der Unterseite der Muldenplatte 19 ist eine Bodenwanne 29 der Gaskochmulde 1 beispielsweise mittels einer Klebverbindung gehaltert Die Bodenwanne 29 begrenzt zusammen mit der Muldenplatte 19 einen Muldeninnenraum 31, in dem eine nicht dargestellte Zündeinrichtung sowie Gasleitungen 33 mit zugeordneten Gasdusen 35 sowie Gasluftgemischleitungen 37 der Gasbrenner angeordnet sind Hierbei wird in bekannter Weise Gas von den Gasdusen 35 in die Gasluftgemischzuleitungen 37 ausgestoßen Mittels einer Injektionswirkung wird sogenannte Pnmarluft zusammen mit dem ausgestoßenen Gas in die Gasluftgemischleitungen 37 gefuhrtA bottom pan 29 of the gas hob 1 is held on the underside of the hob plate 19, for example by means of an adhesive connection. The bottom pan 29, together with the hob plate 19, delimits a trough interior 31 in which an ignition device (not shown) and gas lines 33 with associated gas nozzles 35 and gas-air mixture lines 37 of the gas burners are arranged Here, gas is ejected in a known manner from the gas nozzles 35 into the gas-air mixture supply lines 37. By means of an injection effect, so-called primary air is fed into the gas-air mixture lines 37 together with the ejected gas
Um eine ausreichende Primarluftzufuhr zu den Gasluftgemischleitungen 37 der Gasbrenner zu gewahrleisten, sind in der Bodenwanne 29 Pπmarluftoffnungen 39 vorgesehen, wie sie in der Figur 3 gezeigt sind Die Primarluftoffnungen 39 verbinden einen Raum 41 außerhalb der Bodenwanne 29 mit dem Muldeninnenraum 31 Dadurch ist eine Luftkonvektionsströmung I vom Raum 41 in den Muldeninnenraum 31 und damit in einen Luftansaugbereich der Gasdusen 35 gesichert In dem Raum 41 außerhalb der Gaskochmulde ist ein Kuchenmobelstuck, etwa ein Unterbauschrank 43 vorgesehen, wie er schematisch in der Figur 2 angedeutet istIn order to ensure an adequate supply of primary air to the gas-air mixture lines 37 of the gas burners, primary air openings 39 are provided in the base trough 29, as shown in FIG. 3. The primary air openings 39 connect a space 41 outside the base trough 29 to the trough interior 31. This results in an air convection flow I secured from the space 41 into the interior of the trough 31 and thus into an air intake area of the gas nozzles 35 In the space 41 outside the gas hob, a piece of cake furniture, for example a base cabinet 43, is provided, as is indicated schematically in FIG
Aus der Figur 3 geht hervor, dass in der Muldenplatte 19 als Druckausgleichsleitung Luftoffnungen 45 vorgesehen sind Die in der Figur 2 zwischen der Seitenwand 21 und der Bodenwanne 29 vorgesehene Luftoffnung 45 mundet einerseits unmittelbar in den Raum 41 außerhalb der Gaskochmulde 1 sowie in den Freiraum 27 Zusatzlich ist in der rechten Seite der Figur 2 eine Luftoffnung 45 dargestellt, die in einen Verbindungskanal 47 mundet Der Verbindungskanal 47 ist durch den Muldeninnenraum 31 gefuhrt ist und im wesentlichen luftdicht von dem Muldeninnenraum 31 getrennt Eine hermetisch luftdichte Trennung zwischen dem Verbindungskanal 47 und dem Muldeninnenraum 31 ist dabei nicht erforderlich Vielmehr soll durch die Trennung bezweckt werden, dass Druckstoße größtenteils über den Verbindungskanal 47 in den oberhalb der Muldenplatte 19 vorgesehenen Freiraum 27 - und nicht in den Muldeninnenraum 21 - übertragen werden Oberhalb der Luftöffnungen 45 ist, wie es aus den Figuren 2 und 3 hervorgeht, eine Luftfuhrungsplatte 49 angeordnet, die über einen Zwischenraum 50 von der Muldenplatte 19 beabstandet ist. Die Luftfuhrungsplatte 49 weist gemäß der Figur 2 einzelne Segmente auf, die zueinander in Anlage sind. Durch die Aufteilung in Segmenten ist die Handhabung der Luftfuhrungsplatte 49 bei der Reinigung vereinfacht und ist beispielsweise deren Platzbedarf in einer Spülmaschine reduziert. Jedes Segment der Luftfuhrungsplatte 49 ist mit einer Durchführungsöffnung 51 versehen, durch die der Brennerkopf eines der Gasbrenner ragt. Am Brennerkopf ist eine nach außen kegelstumpfförmig erweiterte Schürze 53 gehaltert. Die Schürze 53 überdeckt Lufteintrittsöffnungen 56, durch die Luft in eine Innenkammer 8 des Zweikreisbrenners und damit in einen Flammenbereich eines Innenbrenners 10 geführt ist. Wie in der Figur 3 gezeigt ist, liegt die Schürze 53 auf einem Randbereich der Durchführungsöffnung 51. Der Randbereich der Durchführungsöffnung 51 ist nach oben gebogen, damit auf die Luftfuhrungsplatte 49 tropfendes Gargut nicht über die Durchführungsöffnung 51 in den Zwischenraum 50 eindringen kann.It can be seen from FIG. 3 that air openings 45 are provided in the trough plate 19 as a pressure compensation line. The air opening 45 provided in FIG. 2 between the side wall 21 and the floor trough 29 flows directly into the space 41 outside the gas hob 1 and into the free space 27 In addition, an air opening 45 is shown in the right-hand side of FIG 31 is not necessary. Rather, the purpose of the separation is that pressure surges are largely transmitted via the connecting channel 47 into the free space 27 provided above the trough plate 19 - and not into the trough interior 21 As can be seen from FIGS. 2 and 3, an air guide plate 49 is arranged above the air openings 45 and is spaced apart from the trough plate 19 via an intermediate space 50. According to FIG. 2, the air guide plate 49 has individual segments which are in contact with one another. The division into segments simplifies the handling of the air guide plate 49 during cleaning and, for example, reduces its space requirement in a dishwasher. Each segment of the air guide plate 49 is provided with a passage opening 51 through which the burner head of one of the gas burners projects. An apron 53 which is expanded in the shape of a truncated cone is held on the burner head. The apron 53 covers air inlet openings 56 through which air is guided into an inner chamber 8 of the dual-circuit burner and thus into a flame area of an inner burner 10. As shown in FIG. 3, the apron 53 lies on an edge region of the feed-through opening 51. The edge region of the feed-through opening 51 is bent upward so that food to be dripped onto the air guide plate 49 cannot penetrate into the intermediate space 50 via the feed-through opening 51.
Aus den Figuren 2 und 3 ist weiter ersichtlich, dass eine nach oben gebogene Stirnseite 54 der Luftfuhrungsplatte 49 durch einen Luftspalt 55 von der hochgezogenen Seitenwand 21 beabstandet ist. Der Abstand a1 zwischen der Stirnseite 53 der Luftfuhrungsplatte 49 und der hochgezogenen Seitenwand 21 liegt in dem gezeigten Ausführungsbeispiel bei etwa 20 mm. Unterhalb des Luftspalts 55 weist die Muldenplatte 19 eine rinnenartige Vertiefung 57 auf, die zwischen der Seitenwand 21 und der Luftöffnung 45 ausgebildet ist. Von den Gargutbehältnissen austretendes Kochgut, wie etwa Milch, Fettspritzer oder überkochendes Wasser gelangt somit durch den Luftspalt 55 hindurch in die Vertiefung 57 und wird dort gesammelt. Dadurch ist verhindert, dass das Kochgut durch die Luftöffnungen 45 auf den Unterbauschrank 43 tropft.It can also be seen from FIGS. 2 and 3 that an upwardly curved end face 54 of the air guide plate 49 is spaced apart from the raised side wall 21 by an air gap 55. The distance a 1 between the end face 53 of the air guide plate 49 and the raised side wall 21 is approximately 20 mm in the exemplary embodiment shown. Below the air gap 55, the trough plate 19 has a groove-like depression 57, which is formed between the side wall 21 and the air opening 45. Cookware emerging from the food containers, such as milk, fat splashes or boiling water, thus passes through the air gap 55 into the recess 57 and is collected there. This prevents the food from dripping through the air openings 45 onto the base cabinet 43.
Während eines Betriebes des in der Figur 2 gezeigten Zweikreisbrenners 7 erwärmt sich die Gaskochmulde. Dadurch steigt Luft aufgrund von Wärmekonvektion vom unteren Raum 41 zur Gaskochmulde auf. Von der aufsteigenden Luft strömt ein erster Teil I über die Primärluftöffnungen 39 in den Muldeninnenraum 31. Ein Hauptanteil der aufsteigenden Konvektionsluft gelangt durch die Luftöffnungen 45 sowie durch die Verbindungskanäle 47 in den Zwischenraum 50. Über den Zwischenraum 50 wird ein zweiter Teil II der Konvektionsluft in die Innenkammer 8 des Zweikreisbrenners 7 geführt. Dort gewährleistet sie als sogenannte Sekundarluft eine ausreichende Flammenbildung am Innenbrenner 10 Die verbleibende Konvektionsluft tritt durch den Luftspalt 55 aus dem Zwischenraum 50 und strömt entlang der hochgezogenen Seitenwand 23 als eine Kuhlluftstromung IM nach oben, wodurch eine Uberhitzung der Seitenwand 23 und damit der Betatigungselemente 17 vermieden istDuring operation of the dual-circuit burner 7 shown in FIG. 2, the gas hob heats up. As a result, air rises from the lower space 41 to the gas hob due to thermal convection. A first part I of the rising air flows into the trough interior 31 via the primary air openings 39. A major part of the rising convection air reaches the intermediate space 50 through the air openings 45 and through the connecting channels 47. A second part II of the convection air flows in via the intermediate space 50 the inner chamber 8 of the dual-circuit burner 7 out. There it ensures, as so-called secondary air, sufficient flame formation on the inner burner 10. The remaining convection air exits through the air gap 55 from the intermediate space 50 and flows upward along the raised side wall 23 as a cooling air flow IM, thereby preventing the side wall 23 and thus the actuating elements 17 from overheating is
Beim Öffnen/Schließen des unterhalb der Gaskochmulde angeordneten Unterbauschranks 43 werden Druckstoße erzeugt Die Druckstoße werden durch die Luftoffnungen 45 bzw die Verbmdungskanale 47 zur Oberseite der Muldenplatte 19 hm übertragen und verpuffen im Freiraum 27 oberhalb der Muldenplatte 19 Erfindungsgemaß werden die Druckstoße nicht bzw nur teilweise über die Primarluftoffnungen 39 in den Muldeninnenraum 31 geleitet Die Pπmarluftversorgung in die Gasluftgemischleitungen 37 der Gasbrenner ist daher nicht beeinträchtigt Um die Auswirkungen der Druckstoße auf den Muldeninnenraum 31 weiter zu minimieren, ist gemäß der Figur 2 der Stromungsquerschnitt der Primarluftoffnungen 39 um ein Vielfaches kleiner ausgelegt als der Stromungsquerschnitt der Luftoffnungen 45 Dadurch ist es erfindungsgemaß nicht mehr notwendig, die Bodenwanne 29 zum Schutz vor Druckstoßen luftdicht gegenüber dem Raum 41 auszubilden oder zwischen dem Unterbauschrank 43 und der Gaskochmulde einen zusätzlichen Zwischenboden anzuordnen Pressure shocks are generated when opening / closing the undercounter cabinet 43 located below the gas hob. The pressure surges are transmitted through the air openings 45 or the connecting channels 47 to the top of the bowl plate 19 hm and fizzle out in the free space 27 above the bowl plate 19. According to the invention, the pressure surges are not or only partially exceeded the primary air openings 39 are directed into the trough interior 31 The primary air supply into the gas air mixture lines 37 of the gas burners is therefore not impaired. In order to further minimize the effects of the pressure surges on the trough interior 31, the flow cross section of the primary air openings 39 is designed to be many times smaller than that according to FIG Flow cross-section of the air openings 45 According to the invention, it is no longer necessary to make the floor pan 29 airtight in relation to the space 41 to protect against pressure surges or to add one between the base cabinet 43 and the gas hob to arrange intermediate shelf
